Multipath routing technique for responding to sniffing attacks in wireless multimedia sensor network environment

초록

As the image sensor modules such as complementary metal oxide semiconductor (CMOS) camera sensors and digital microphones are developed, security is required such as data storage and transmission in wireless multimedia sensor network technology and application. Data transmitting through existing sensor network routing path has the problem of high vulnerability to information leakage by sniffing attacks. Therefore, the study proposes one of the protection technique from a sniffing attack, which protects from attacking. The proposed technique is based on the movement of risk factors that sets priority of the geographically proximal sensor nodes according to defense readiness condition (DEFCON) and data importance. According to the simulation results, it achieved approximately 5.8% transmission delay time compared with existing sensor network path but the security was confirmed as eavesdropping rate where risk factors can attack and eavesdrop decreased by approximately 18.5%.
